Really works

7/4/2019 by Meredith

This mug really does cool down your beverage to the right temperature and keep it there for a long time. I have one at home, and am probably going to get another for the office!
It is also very sleek and sturdy. It is a little heavier than I might want in a travel mug since I take public transportation and also walk after work, so I would be carrying it around a lot.

This travel mug is amazing. It really does what it says it does. You pour the hot coffee into the mug, wait 2 minutes, shake, and it is ready at the PERFECT drinkable temperature and it holds it at that temperature for hours. No more waiting to drink your coffee when you are in a hurry to get to work and you won't burn yourself.
I even use it at home when I want to drink out of a cute coffee cup. I pour the freshly hot coffee into the mug, wait 2 minutes and then pour it into my cute coffee cup. I love it. Buy it! It WORKS!

I do not know how it works but it really does.


this mug saves me from microwaving over and over

This mug works! I tried the Ember and many other ways of keeping my coffee warm while i am multitasking and drinking several couples in a day. This mug does drop the temp from very hot within two minutes and it does keep it hot. I don't like reviews as they take time but this one i have to let people know about. it is a valid temp holding mug. use it everyday!More > < Less


It’s Gotta Be Alchemy

Since receiving my Thero, I haven’t been without it. I clean it daily which is well explained in the instructions. I’m convinced there’s some magic going on here. It does exactly what it claims to do. Outstanding product for us coffee lovers. Thanks much.More > < Less

About Thero

Just-Right Coffee

As a grad student, Thero vacuum-insulated mug Maker Chloris Yang was frustrated with burning her mouth on too-hot coffee and then, inevitably, ending up with too-cold coffee after letting it cool off for too long. Chloris put her book-smarts to use to create a solution that prevents both of those unsavory scenarios.

Thero cools scalding hot coffee down to an ideal 140 degrees Fahrenheit in under two minutes and keeps it there for up to five hours. Science is doing the temperature-controlling work here, thanks to phase change material (also known as PCM) sealed inside double-walled stainless steel. It quickly absorbs heat from the coffee and slowly releases it back to maintain that magical temperature.

Chloris put thought into the design of the lid, too, and made it spill- and leak-proof, and easy to use with one hand. So every sip can be a perfect one.
